Open the dog's ear and see if there is any foreign body inside. Rub the cotton swab gently in the dog's ear, and then smell the cotton swab for any odor. If there is an odor, it is ear mites.
? Ear mites, also known as ear mites, are common ear canal parasites in cats and dogs. Most cases are parasitic in the ear canal, and a few cases also appear in the head, neck and tail.
Ear mites are highly contagious between cats and dogs and spread through close contact. A cat or dog at home is infected with ear mites, and all cats and dogs need to start treatment at the same time. Although dogs and cats of any age can be infected, most of them are very young. Cats are more susceptible to infection than dogs. In rare cases, people will have red skin. Generally speaking, it is extremely unlikely that people will have symptoms due to pet ear mites.
